Be it known thet I, LESLIE C. DUTRO, a citizen of the Unifitl States, and a resident of Long Beach, in the county of Les Angelesa d State of California, have invented a new and lrnproveii- Oil Cup, ot" which the following is a full, clear ancl exact description.

' This invention relates to improvements in oil cups, and more particularly to oil cups having an automatic feed of oil controlled by the temperature of the hearing.

A further object is to provide an oil-feed ing device of the character stat-ed, which can be manufactured and sold at an extremely low price, which will feed oil as the bearing increases in temperature and which will automatically cease feeding the oil as the temperature of the bearing falls.

With these and other objects in View the invention consists in certain novel features of construction, and combinations and arrangements or" parts as will be more fully 'hereinei ter described and pointed out in the claims. The accompanying longitudinal section vention.

1 represents my improved oil cup which is provided at its upper end with an inlet nipple 2, the letter externally screw threaded as shown at 3, for the receptiouof a cap 4: and a gasket 5 to securely close the inlet and render the cup airtight. It is obvious, of course, that the particular form of'inlet and the manner of makingthe same airtight may be varied without departing from my drawing is a viewin illustrating my 111- invention.

The closed bottom 6 of the cup 1 is made centrally wither! integral well 7, the latter externally screw threaded as shown at 8, and adapted to screw into a, threaded opening 9 in a bearing 10. A vertical well outlet tube 11 is securegl in the bottom 12 cf the.

well. and is open to the bearing and this tube 11 projects upwardly into the well the clesired distance.

A cup outlet tube 13' is secured in the bottom of the cup 1 cifiilmunicating with the interior of the cup and projects downwardly into the well 7.

1%- represents the lubricant which is located in the cup 1 and which overflows into the well 7 and from the latter flbws into the bearing 10 through the tube 11.

This expansion will force the lubricant downwardly through the tube 13 into the well 7 and will overflow through the tube 11 into the bearing 10 to cool the latter? As the temperature decreases, the expansion of the fluid will decrease, and if this decrease in temperature is sufiicient, the lu hricarit will be suckerl'up from the well Y through the tube 13 and air will be drawn from the bearing through the tube 11. into the well. The feed of lubricant is, therefore, controlled automatically by the temper eture of the bearing and in carrying out this automatic operation, the metal of the cup as well esthe-lubricant and the air expand and contract in accordance with the temperature of the bearing so that the feecl will fiow into the well 7, but

The well 7 allows l eway in the operation of the cup. This leeway may be accom plishell by extending or shortening the tube 13. By lengthening the tube 13 so that it terminates near the bottom of the well, the well has to be filled up to a point level with the top of the tube 11 before it begins to feed to the bearing, and when a contraction takes place in the well, the liquid is cirewn up into the cup until a point level with the bottom of the tube "13 is reached, when direct communication with the atmosphere is made through the tube 11 and the hearing 10 so thet the oil in the well is drawn up into the cup. i I

A further advantage of the enclosed well is that when the cup is jcrrecl or shaken, insteerl of shaking it few drops directly out into the bearing, are shaken from the cup into the well wh n he'balsiice is establishezl, ica'nt is drawn ELJNHTEE); TATE rarer caries.

EMULSION AND PROCESS OF MAKING THE SAME.

No Drawing.

T 0 all whom it may concern:

Be it known that l, CHARLES S. REEVE, a citizen of the United States, residing at Grantwood, in the county of Ber en and State of New Jersey, have invente certain new and useful Improvements in Emulsions and Processes of Making the Same, of which the following is aspecification.

This invention relates to bituminous materials. It relates especially to bituminous materials of a liquid or semi-liquid nature which contain clay or similar material.

The object of the invention is to produce an aqueous emulsion of bituminous materials which shall be more stable than similar emulsions heretofore produced. Another.

object of the invention is to produce a process by which the bituminous materialcan be suspended in the aqueous dispers medium for a longer eriod than has heretofore been possible W1th the usual processes.

It has been known for a long time that an emulsion could be produced by mixing clay, water, and bituminous materials and stirring the same, whereupon a certain proportion of the bituminous material and the clay would become permanently suspended in the water and would not settle upon long standing. It has been found for example that when an emulsion of about 4: parts soft coal tar pitch having a melting point of 100110 F. (by cube in water method), 3 parts of clay and 3 parts of water were dispersed in 9 parts of water to one part of this emulsion, about 65% by volume of this mixture would remain in suspension at the end of ten minutes. Such emulsions are unsatisfactory, however, because there is a tendency for the materials to settle out upon long standing, and it is also impossible to procure the concentration of bituminous material in the emulsion that is sometimes desirable.

By the present invention a mixture of bituminous material such as asphalt, coal tar, etc., and argilliferous materials such as I clay, is made to form an emulsion in water in such a manner that upon dispersion in water a larger percentage of bitumen and clay will be retained in suspension than in the old processes. In order to bring about this result, I have foundthat when ammonium hydroxide is added to the water the product is very much improved in the respects above mentioned,

Specification of Letters Patent.

Application filed July 23, 1920. Serial No. 398,391.

In order to make the invention more clearly understood, the following specific example is given for illustrative purposes but it is not intended to restrict the invention to the exact proportions or materials herein mentioned. For example, an emulsion of the same materials and proportions above described may be prepared excepting for the addition of ammonium l1 droxide to the amount of about 0.25% o the weight of the emulsion. Upon dispersing this emulsion in 9 parts of water to 1 part of emulsion, it has been found that about 90% by volume of the mixture would remain in suspension at the end of 10 minutes as compared w1th 65% when the hydroxide was omitted. The proportion of ammonium hydroxide has been varied from about 2/10 of one per cent to forty-five hundredths of one per cent or higher, but no noticeable improvement has been found-by using proportions of hydroxide greatly in excess or" the latter amount. The proportions of bituminous material and clay may also be varied over a, wide range with satisfactory results,

since in allcases the addition of the hy droxide tends to make the emulsion more permanent. Although i a relatively soft pitch has been described in this specification, I have obtained similar results with harder pitches. I therefore do not desireto limit myself to soft pitch but include any residue obtained by the distillation of tar.

Another advantage of using the hydroxide as set forth in this invention is that it causes a more rapid set or hardening of the composition when it is subjected to a drying operation.

The composition or emulsion produced as above set forth can be used in its fluid or simi-fiuid condition as a paint or coating and when so applied, the water dries out and the hydroxide causes the layer to harden quite rapidly. Also, the emulsions which contain no ammonia break down more quickly and readily than those which contain it. So far ammonium hydroxide has given decidedly the most satisfactory results, but sodium hydroxide or potassium hydroxide may be used to some advantage.
